jBoss EAP 6.1.Final Playing with HTTP Headers and causing NullPointerException
I am porting my RESTful service from jBoss EAP 5.X to jBoss EAP 6.1 which uses Wink. It works absolutely perfectly on jBoss EAP 5.1
Initially when I deployed my service in jBoss EAP 6.1.Final I got exception as 'More than one JAX-RS implementation found POST_....', I searched and found a post which says I have to disable the jBoss ReastEay scanner to over come the problem so I have added following in my web.xml;
<context-param> <param-name>resteasy.scan</param-name> <param-value>false</param-value> </context-param> <context-param> <param-name>resteasy.scan.providers</param-name> <param-value>false</param-value> </context-param> <context-param> <param-name>resteasy.scan.resources</param-name> <param-value>false</param-value> </context-param>
And my previous error gone but I still get an WARN upon server startup which I am not sure if related (but its pasted below just in case)
16:52:44,629 WARN [org.jboss.as.ee] (MSC service thread 1-3) JBAS011006: Not installing optional component org.apache.cxf.transport.http.Servlet3Cont inuationProvider$Servlet3Continuation due to exception: org.jboss.as.server.deployment.DeploymentUnitProcessingException: JBAS011054: Could not find d efault constructor for class org.apache.cxf.transport.http.Servlet3ContinuationProvider$Servlet3Continuation at org.jboss.as.ee.component.ComponentDescription$DefaultComponentConfigurator.configure(ComponentDescription.java:607) [jboss-as-ee-7.2.0.Fin al-redhat-8.jar:7.2.0.Final-redhat-8] at org.jboss.as.ee.component.deployers.EEModuleConfigurationProcessor.deploy(EEModuleConfigurationProcessor.java:80) [jboss-as-ee-7.2.0.Final- redhat-8.jar:7.2.0.Final-redhat-8] at org.jboss.as.server.deployment.DeploymentUnitPhaseService.start(DeploymentUnitPhaseService.java:120) at org.jboss.msc.service.ServiceControllerImpl$StartTask.startService(ServiceControllerImpl.java:1811) at org.jboss.msc.service.ServiceControllerImpl$StartTask.run(ServiceControllerImpl.java:1746) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1110) [rt.jar:1.7.0] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603) [rt.jar:1.7.0] at java.lang.Thread.run(Thread.java:722) [rt.jar:1.7.0]
Now when I am trying to access my service URL via POSTMan (Simple Rest Client) I get following exception;

I used TCPMon to capture my request from client it seems to have all the necessary header information as follows;
GET /hothouse-iris/Hothouse.svc/ HTTP/1.1 Host: 127.0.0.1:9090 Connection: keep-alive Authorization: Basic U1NPVVNFUjE6MTIzNDU2 Cache-Control: no-cache User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/30.0.1599.69 Safari/537.36 Content-Type: application/atom+xml Accept: */* Accept-Encoding: gzip,deflate,sdch Accept-Language: en-GB,en-US;q=0.8,en;q=0.6 Cookie: JSESSIONID=8D9FE5379FE7576610BB4B78A431AD10; __utma=96992031.2145502422.1381922298.1382004674.1382006170.4; __utmc=96992031; __utmz=96992031.1381922298.1.1.utmcsr=(direct)|utmccn=(direct)|utmcmd=(none)
I have tried to enable the HTTP Access Logs as follows;
<subsystem xmlns="urn:jboss:domain:web:1.4" default-virtual-server="default-host" native="false">
<connector name="http" protocol="HTTP/1.1" scheme="http" socket-binding="http"/>
<virtual-server name="default-host" enable-welcome-root="true">
<alias name="localhost"/>
<alias name="example.com"/>
<access-log pattern="%h %l %u %t %r %s %b %{User-Agent}i %{JSESSIONID}c">
<directory relative-to="jboss.server.log.dir" />
</access-log>
</virtual-server>
</subsystem>
But its not printing the HTTP Headers received by the server and what are being passed to the service.
Could you please help me solve this issue. Thanks
